Verification of Pipe Flow Expert Calculation Results

Pipe Flow Expert Software - Non-Compressible Results Verification

The Pipe Flow Expert software calculation results using the non-compressible calculation engine (with Colebrook-White friction factors and Darcy-Weisbach equation) have been verified by comparison to published results data from a number of well known sources. In all 50 test cases, the Pipe Flow Expert software results compared very favourably.

The Pipe Flow Expert software calculation results using the compressible gas flow calculation engine (various compressible flow equations, including the General Flow Equation, Complete Isothermal Equation, AGA Equation, Panhandle A Equations, Panhandle B Equations, Weymouth Equations, and others) have been verified by comparison to published results data from a number of well known sources. In all 25 plus test cases, the Pipe Flow Expert software results compared very favourably.

It can also be checked that the Pipe Flow Expert calculation results agree with the fundamental equations for pressures and flows in pipe networks. This includes comparison to the governing flow continuity equations and the conservation of energy equations that follow pressure losses around loops in a pipe network.

The Pipe Flow Expert results have also been compared to results produced by other analytical methods and they have been found to be in good agreement.

Pipe Flow Expert is currently used by engineers in over 100 countries worldwide.

The trial version of the Pipe Flow Expert software allows the user to draw systems with up to 5 pipes. The user can then check the results from these systems against their own known data to confirm that Pipe Flow Expert produces the answers they expect.

The software also contains a number of example systems with more than 5 pipes, which can be solved, even in trial mode. The results obtained from solving these networks can be verified by solving the same system using a different method or program and comparing the results.
